Describe the bug

Using find_package(CUDAQ REQUIRED) in a CMake project results in the following error

-- The CUDA Quantum compiler identification is NVQ++ - /opt/nvidia/cudaq/bin/nvq++
-- Number of NVIDIA GPUs detected: 1
-- CUDA Quantum Target = nvidia
-- Configuring done
CMake Error: Error required internal CMake variable not set, cmake may not be built correctly.
Missing variable is:
CMAKE_CUDAQ_CREATE_SHARED_LIBRARY
CMake Error: Error required internal CMake variable not set, cmake may not be built correctly.
Missing variable is:
CMAKE_CUDAQ_CREATE_SHARED_LIBRARY
-- Generating done
CMake Generate step failed.  Build files cannot be regenerated correctly.

Steps to reproduce the bug

Using the latest image and include include find_package(CUDAQ REQUIRED) in your CMake project.

Expected behavior

I would assume that CMAKE_CUDAQ_CREATE_SHARED_LIBRARY should be set, since I am not sure what provide. It seems that On or Off does not work.

Is this a regression? If it is, put the last known working version (or commit) here.

Not a regression

Environment

• CUDA-Q version:
• Python version:
• C++ compiler:
• Operating system:

I think I have resolved this for Patrick. Needed to add set_target_properties(LIB_NAME PROPERTIES LINKER_LANGUAGE CXX) to CMake to get C++ libraries to link properly. Waiting on Patrick to confirm this works for him.
